What are the loop control elements of a while loop?

Loop Control -- for, while, continue, break Use the for statement to loop a specific number of times. The while statement is more suitable for basing the loop execution on how long a condition continues to be true or false. The continue and break statements give you more control on exiting the loop.

What is while loop example?

A "While" Loop is used to repeat a specific block of code an unknown number of times, until a condition is met. For example, if we want to ask a user for a number between 1 and 10, we don't know how many times the user may enter a larger number, so we keep asking "while the number is not between 1 and 10".

Why do we use while loop?

The while loop is used to repeat a section of code an unknown number of times until a specific condition is met. For example, say we want to know how many times a given number can be divided by 2 before it is less than or equal to 1. ... additionally, keep a count of how many times we do the division.
